The Lowdown
Alright folks, it's Rusty here. Let's be straight with you: the next couple of weeks look pretty quiet for the southern Maine coast. We're looking at a long stretch of tiny, weak surf with not much to get excited about. I'm not gonna sugarcoat it.
For the first week and a half, from Thursday the 6th right through to about Tuesday the 18th, it's a lean run. The swell is barely a ripple, mostly under 2 feet and coming from the southeast. The energy is flat, with combined swell energy readings barely cracking 20 or 30 (weak), which is basically just a lake with a light breeze. Winds are a mix of cross and cross-onshore, making it a messy, choppy affair. The best you'll see in that stretch is a couple of glassy mornings on the 7th and the 16th, but with waves only 0.7 feet to 1.0 feet, even a longboard will be struggling to get a glide. For a beginner, that ankle-snapper isn't worth the paddle.
Now, there's a little glimmer of hope on the 19th, which is a Wednesday. Kennebunk Beach (Kennebunk Beach) will see a bump in swell to 4 feet from the SSE. The combined energy jumps to a moderate 145, which is a big step up. The wind will be blowing offshore out of the NNE, which is the key here, making for clean, peeling faces. The water temp is about average for this time of year. It's still not a world-beater, but it's the only time in the whole window where the conditions line up for a proper surf. The SSE swell direction isn't perfect for this sheltered ENE-facing spot, but with that offshore wind, it'll be the best we've got. Keep in mind this is a beach break that's fairly consistent, so it won't be a dartboard, but it's not a point break either. With the crowds being "sometimes," you might not have it all to yourself.
Beyond that, the 20th and 21st look like we're back to small, weak surf with less favorable winds. If you're a beginner, the 4 feet on the 19th might be a touch big, but it's the cleanest wave of the forecast. For the experts, it's not quite big enough to get the heart pumping, but it's a welcome break from the nothingness.
So, to wrap it up: hold your horses for a week and a half. The 19th is your day. It's a one-day standout, clean and promising, but don't bet the farm on it being epic. Everything else is a bust.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
